What is the definition of the adjacent side in a right triangle?

Back

The adjacent side is the side next to the angle of interest (not the hypotenuse).

Front

What is the definition of the hypotenuse in a right triangle?

Back

The hypotenuse is the longest side of a right triangle, opposite the right angle.

Front

What is the definition of the opposite side in a right triangle?

Back

The opposite side is the side opposite to the angle of interest.

Front

What does SOH CAH TOA stand for?

Back

SOH: Sine = Opposite/Hypotenuse; CAH: Cosine = Adjacent/Hypotenuse; TOA: Tangent = Opposite/Adjacent.

Front

How do you calculate the cosine of an angle in a right triangle?

Back

Cosine of an angle = Adjacent side / Hypotenuse.

Front

How do you calculate the sine of an angle in a right triangle?

Back

Sine of an angle = Opposite side / Hypotenuse.

Front

How do you calculate the tangent of an angle in a right triangle?

Back

Tangent of an angle = Opposite side / Adjacent side.
